Abstract: In this paper, the impacts of heavy loads, with intermittent non-linear nature, on the stability/security of microgrids operating in an islanded mode will be investigated. The microgrid architecture under study is assumed to have a renewable energy source, a storage system and multiple emergency generators. The impact of non-liner loads will be studied during normal operating conditions, and in the case of various contingencies. Moreover, a solution to mitigate the effect of these non-linear loads based on storage distribution will be discussed.

Keywords: Islanded-mode, microgrid, pulsed loads, security, stability, storage distribution
